Platte River Networks (PRN) is the computer company that has been managing Clinton’s private server since June 2013. Politico reports that it has declined requests by the Senate Homeland Security Committee to interview five employees about the security of Clinton’s server.

Additionally, Datto, Inc. was employed by PRN to back up data from the server. On October 6, 2015, McClatchy Newspapers quoted Datto’s attorney who said the company had permission from representatives of Clinton and Platte River to cooperate with the FBI investigation. But on October 19, 2015, Datto told the committee that it can’t answer questions from the committee because it has a confidentiality agreement with its client PRN and can only answer questions about that account with their permission. PRN gave permission initially but then changed its mind.

PRN spokesperson Andy Boian says that the interview requests from Congress weren’t “formal” inquiries, even though request letters were delivered on official Senate letterhead. He adds, “We as a company have felt like we have done everything we can to comply with every request by both the FBI and the Homeland Security Committee, and we really have nothing left to give.”

Tania Neild, CEO of the technology broker company InfoGrate, helped Clinton select PRN to run their server. She declined to be interviewed by Congressional investigators, invoking a nondisclosure agreement she had with her client.

Another computer company, SECNAP, was involved in the security of the server. They apparently aren’t cooperating with Republican investigators either, because Dennis Nowak, a lawyer for SECNAP, says that communications technology companies are governed by a law that imposes criminal and civil penalties for disclosing customer information, and that can only be waived by subpoena, search warrant, court order, or consent of the client.

These four companies apparently have fully cooperated with the FBI. But Politico reports, “While the firms have voluntarily produced some information for Congressional Republicans in the past, now it seems they’re not willing to go beyond their legal obligations when it comes to responding to committee inquiries.”
